[Hiring] Datacenter MEP Field Engineer @Hydra Host

Role Description

Hands-on Field Engineer that owns liquid cooling and HVAC infrastructure in GPU compute environments.

• CDUs, direct-to-chip loops, facility water plants, precision air handling, power distribution, power chain assessment.
• Power analysis management at rack densities where miscalculations take hardware offline.

Qualifications

• Any Journeyman MEP Trade License or higher.

Requirements

• Evaluate and commission liquid cooling for GPU compute—CDUs, direct-to-chip cold plates, reardoor HX, immersion tanks, and chilled water plants.
• Size heat rejection from real TDP data, not marketing sheets.
• PDU/UPS/XFR/ATS/STS Medium Voltage to Low Voltage transformation, inversion, rectification, power distribution one-lines.
• CRAH/CRAC/CDUs, hot/cold aisle containment, economizers, humidification, and supplemental cooling for mixed air/liquid deployments.
• Spec piping for liquid cooling loops—routing, glycol concentration, pump curves, flow balancing, filtration, expansion tanks, and leak detection.
• Thermal validation under load—delta-T, flow rate verification, coolant pressure testing, refrigerant charge validation.
• Coordinate with mechanical subs, vendors, and controls integrators. Catch trade conflicts before they become change orders.

Preferred Skills and Responsibilities

• DCIM/BAS integration for cooling monitoring and electrical capacity management.
• Several years of datacenter mechanical/electrical installation, and commissioning.
• Hands-on liquid cooling experience at 75+ kW/rack—CDUs, direct-to-chip, rear-door HX, or immersion.
• Familiarity with N+1/2N redundancy architectures for cooling plants and concurrently maintainable designs.
• Willing to travel for site surveys, construction oversight, and commissioning.

Portfolio (Highly Advantageous)

• Show us projects you designed or delivered.
• CDU install docs, HVAC load calcs, One-Line Power Train diagrams, commissioning reports with thermal data, piping schematics, conduit installations, construction photos, capacity models.
• Personal site, portfolio, or reference list of completed facilities.
